Definitions

  • the present invention relates to a closure element for a liquid container, wherein the closure element comprises a closure cap, wherein the closure cap has a cap lid, wherein the closure cap has a cap mantle extending circumferentially to the cap lid and cylindrically around a closure cap axis, wherein the closure cap comprises a sealing ring, wherein the sealing ring is arranged on the inside of the cap lid, wherein the closure element comprises an anchor ring and a connecting element, wherein the connecting element connects the closure cap to the anchor ring in a tensile-resistant manner, wherein the anchor ring is designed such that it can be brought into tensile-resistant engagement with a container neck of a liquid container.
  • the present invention further relates to a combination of a container with a closure element of the type mentioned at the outset.
  • Closure elements of the type mentioned above are also called tied closures. This is because they can be engaged with the neck of a container, so that the closure cap always remains attached to the container neck, even when the closure cap is in an open position and liquid is flowing out of the container.
  • the container to be sealed is a beverage container and is intended for a consumer to drink the contents directly by placing their mouth on the neck of the container, it is important that the cap can be opened to a position in which it interferes with the consumer's drinking as little as possible.
  • a container lid made of synthetic resin which includes a deformation prevention device in the middle area of the inner surface of the upper wall.
  • an object of the present invention is to eliminate or at least reduce the risk of liquid residues escaping from an open, attached closure cap.
  • a closure element for a liquid container wherein the closure element comprises a closure cap, the closure cap having a cap lid, the closure cap having a cap mantle extending cylindrically around a closure cap axis and adjoining the cap lid circumferentially, the closure cap comprising a sealing ring, the sealing ring being arranged on the inside of the cap lid, the closure element comprising an anchor ring and a connecting element, the connecting element connecting the closure cap to the anchor ring in a tensile-resistant manner, the anchor ring being designed such that it can be brought into tensile-resistant engagement with a container neck of a liquid container, and the cap lid having a structured surface on its inside and radially inside to the sealing ring at least in sections, the structured surface being designed such that the structured surface comprises a plurality of open recesses for receiving liquid.
  • the textured surface exerts greater adhesive forces on any liquid residue remaining in the cap, particularly on the cap lid, after opening than would be the case with a largely smooth inner surface. This allows the liquid residue to be retained in the recesses formed by the textured surface, even as gravity pulls it towards the openings.
  • the sealing ring is also known in technical circles as a sealing olive or sealing lip.
  • the sealing ring is designed to rest against the inside of a container neck. and seals the container neck against the external environment when the closure element is applied to the container neck in a closed position.
  • the connecting element connects the closure cap to the anchor ring with such tensile strength that the resulting connection only breaks at a tensile force of 12.5 Newtons or more.
  • the cap cover is designed as a cover plate extending essentially perpendicular to the closure cap axis.
  • the connecting element is a hinge element which is designed such that the closure cap can be pivoted about a pivot axis which is formed essentially perpendicular to the closure cap axis relative to the anchor ring.
  • the connecting element comprises at least one retaining strap and preferably two retaining straps.
  • the structured surface borders the sealing ring, wherein the structured surface preferably borders the sealing ring at every circumferential angle position.
  • liquid residues after opening the cap are primarily located in the inner transition area between the sealing ring and the cap lid. This is also due to the locally increased adhesive forces in this area caused by the sealing ring. Liquid residues are significantly less common in the central area of the cap lid, as the adhesive forces acting solely on the inner surface of the cap lid are generally insufficient to prevent backflow of liquid into the container when the container is stored upright before opening.
  • the structured surface being adjacent to the sealing ring, not only further intensifies the locally acting adhesive forces in this area. Simultaneously, the structuring also weakens the molecular forces acting circumferentially within a liquid residue, which hold the residue together.
  • a substantially continuous film does not form along the transition area between the sealing ring and the cap lid over a larger circumferential angle. This also ensures that the amount of liquid contained in a recess defined by the structured surface does not exceed a critical mass value, beyond which the adhesive forces would no longer be sufficient to compensate for the force of gravity acting on the amount of liquid.
  • the cap lid has several structural elements on its inner surface, the surfaces of which define the majority of open recesses.
  • a structural element is a plastic element with a clearly definable spatial extent, such as height, length, and width.
  • such structural elements have the advantage that they generate a clearly definable adhesive effect, which can then be distributed, for example, homogeneously along the transition area between the sealing ring and the cap lid.
  • the structural elements have a smaller distance to the closure cap axis than the sealing ring.
  • the structural elements are formed in one piece with the cap cover and the sealing ring.
  • each of the plurality of open recesses forms a capillary.
  • the design of the recesses as capillaries ensures that, in the majority of all cases when using the closure element, the adhesive forces compensate for the force of gravity acting on liquid residues on the cap lid.
  • the first pair of structural elements is designed and arranged such that a capillary force acts on a quantity of cow's milk entering the first capillary during the use of the closure device, which substantially compensates for the force of gravity acting on the quantity of cow's milk when the inside of the cap lid is oriented towards the ground.
  • each pair of adjacent structural elements has a circumferential distance of 2 to 10 degrees in radians. It has been found that such radian distances can generate sufficient adhesion to reduce the risk of liquid residue dripping from an open closure cap.
  • each pair of adjacent structural elements has a circumferential distance of 4 to 8 degrees in radians. It has been found that such radian distances can generate sufficient adhesion force to significantly reduce the risk of liquid residue dripping from an open closure cap.
  • each pair of adjacent structural elements has a circumferential distance of no more than 2 mm from each other. This creates recesses between the structural elements, as defined in the present invention, which provide sufficient adhesion to reduce the risk of liquid residue dripping. At the same time, the material required for attaching the structural elements is kept to a minimum.
  • each pair of adjacent structural elements has a maximum circumferential distance of 1.5 mm from each other. This further enhances the adhesive effect, thus further reducing the risk of dripping.
  • each pair of adjacent structural elements has a maximum circumferential distance of 1 mm from each other. This ensures that in the majority of all everyday situations, dripping of liquid residues does not occur.
  • the several structural elements are elongated ribs.
  • Such ribs are very well suited for forming recesses in the form of valleys. Furthermore, such ribs can be produced very easily using known injection molding processes for plastic closures.
  • the ribs extend substantially radially. This prevents the formation of a continuous liquid film on the cap lid, which would otherwise remain as liquid residue in the closure lid when the lid is opened. Due to the radially extending ribs, the liquid molecules can no longer interact with each other as strongly over a greater distance to form a continuous film, since the necessary planar surface is repeatedly interrupted by the axially projecting ribs. In other words, the ribs particularly prevent the formation of an annular film, as continuous, undisturbed contact between the liquid molecules is not possible due to the interruptions caused by the ribs.
  • the ribs abut both a surface section of the cap lid lying perpendicular to the cap lid axis and an inner surface of the sealing ring arranged cylindrically around the cap lid axis. This advantageously prevents the formation of a film of liquid residue in the transition area between the sealing ring and the cap lid.
  • the ribs extend in the form of a half-circle arc between the surface section of the cap lid lying perpendicular to the closure cap axis and the cylindrical section around the closure cap axis.
  • the inner surface of the sealing ring is arranged in a specific way. Ribs designed in this way are particularly easy to demold during the manufacturing process and require minimal material – while providing maximum adhesion and simultaneously preventing film formation.
  • the semicircular arc can, in particular, have a radius of curvature whose center of curvature is located radially inside the cap shell.
  • the ribs each have a radial extent of 2 to 20 percent of the diameter of the cap lid. It has been shown that film formation can be reduced by appropriately designed ribs to such an extent that the risk of liquid residues with a critical mass required for dripping can be reduced.
  • the ribs each have a radial extent of 5 to 15 percent of the diameter of the cap lid. With appropriate design, it can be ensured that the risk described above is further reduced.
  • the ribs each have a radial extent of 8 to 12 percent of the diameter of the cap lid. This ensures that film formation practically does not occur.
  • the ribs each have a radial extension of 2 mm to 8 mm. In another embodiment of the locking element according to the invention, the ribs each have a radial extension of 2.5 mm to 6 mm. In another embodiment of the locking element according to the invention, the ribs each have a radial extension of 3 mm to 4 mm.
  • the ribs each have a circumferential extent of 0.2 mm to 1 mm. In another embodiment of the locking element according to the invention, the ribs each have a circumferential extent of 0.4 mm to 0.8 mm.
  • the ribs each have a maximum axial extension of 1.5 mm to 4 mm. In another embodiment of the locking element according to the invention, the ribs each have a maximum axial extension of 2 mm to 3 mm.
  • ribs designed according to the parameter ranges described above both advantageously prevent or at least reduce film formation on the cap lid and enable the formation of a plurality of recesses, the recesses being accompanied by adhesive forces which retain any liquid residues contained in the recesses and thus prevent these residues from dripping off.
  • the closure element is made of plastic. In another embodiment of the closure element according to the invention, the closure element is manufactured by an injection molding process.
  • the problem underlying the invention is also solved by a combination of a container with a closure element according to one of the embodiments described above.
  • the container can also be made of plastic.
  • the container has a container neck, wherein the anchor ring is engaged with the container neck in such a way that the anchor ring is tensilely connected to the container neck, so that the closure cap is attached to the container neck via the connecting element and the anchor ring, even when the closure cap is in an open position.
  • the container is a beverage container, in particular a beverage container for milk, milk-based drinks, or fruit juices. It has been found that these types of liquids, in particular, tend to leave larger liquid residues in a cap, so that the risk of leakage is especially high with these types of beverages if the closure elements are not designed according to one of the embodiments described here.
  • the anchor ring engages with the container neck in such a way that the resulting tensile-resistant connection only breaks at a tensile force of 12.5 Newtons or more.
  • FIG. 1 shows a preferred embodiment of the closure element 1 according to the invention.
  • the closure cap 2 used there is a screw cap.
  • the closure cap 2 has an internal thread 12 which can engage with a corresponding external thread of a container neck in order to close the container neck.
  • the liquid-tight seal is further enhanced by the outer sealing element 13, which is located radially further outwards from the sealing ring 5.
  • This outer sealing element is annular in shape and rests against an outer side of the container neck when the closure element 1 is closed. In other words, the container neck is positioned between the sealing ring 5 (inside) and the outer sealing element 13 (outside) to provide a liquid-tight seal.
  • Such a device is necessary to ensure that a liquid container can be transported without any unintended leakage.
  • the container for example a 500 ml PET beverage bottle, is frequently moved from an upright to a horizontal position. or even if the container is turned upside down. In that case, it is crucial that the liquid contents cannot escape from the container neck.
  • the ribs 8 are - as in Figure 1 and 5
  • the ribs are arranged so closely together that adhesive forces act on the liquid residues from the two flanks of the adjacent ribs 8 and the intervening valley floor, counteracting their drainage, even when the cap 2 is stored in an upright position.
  • the risk of drops forming and falling from the cap 2 is low, for example, when a consumer brings a beverage container equipped with the closure element, or its neck, to their mouth to drink.
  • the ribs 8 are designed as half-round arches and attach both laterally to the inside of the sealing ring 5 and axially to the cap cover 3.
  • the cap cover 3, the ribs 8, and the sealing ring 5 are formed in one piece.
  • a groove extends between each adjacent pair of ribs 8 – as shown in Fig. 4 visible - slit-shaped recess 9, which, due to its fluid-retaining function, can also be referred to as capillary 9.
  • Fig. 5 The ribs 8 and the intervening slit-shaped recesses 9 are shown again in a top view from below. It can also be seen that the recesses 9 narrow from the sealing ring 5 towards the axis 50 of the end cap. This is due to the circumferential extent of the ribs 8, which is constant in the radial direction.
  • the anchor ring 6 is designed as a flexible band.
  • This flexible band has a hinged inner band section 10 that can engage with a pilfer-proof ring of a container neck to fix the anchor ring 6 relative to the container neck.
  • a connecting element (not shown in detail) that links the anchor ring 6 to the closure cap 2 ensures that the closure cap 2 remains attached to the anchor ring 6 even when the closure cap 2 is unscrewed from the container neck to release the contents of the liquid container.
